AM2431: AM243x - Secure Boot Support

Praveen Kumar R

Part Number: AM2431
Other Parts Discussed in Thread: LP-AM243

Hi, we're evaluating AM243x Launchpad and AM243x GP EVM to check the secure boot support.

Does only AM243x GP EVM support Secure Boot and other security features since it has HS-FS?

We understand from the SDK documentation. there are two device type GP and HS. The  MCU in AM234x LP of type GP and therefore doesn't support secure boot. 

Our target MCU is AM2341, what are the part numbers that contains HS-FS so that we can ensure Secure boot will be supported? Is this information available in the datasheet?

    Hi Praveen,

    Both the AM243 EVM and LP-AM243 now have HS-FS silicon.  The LP-AM243 LaunchPad was originally offered with GP silicon instead of HS-FS silicon, but the latest update to the AM243 LaunchPad included migrating to HS-FS silicon.  If you take a look at Section 2.6 of the LP-AM243 User's Guide, it describes how to tell if the silicon on your board has GP silicon or HS-FS silicon.  Both the AM243 EVM and LP-AM243 now only ship with HS-FS silicon, so you can order either one and you will receive an HS-FS part.

    My recommendation for determining which EVM to order would be to compare the features of the EVMs with what your intended application is to get the best fit there.  Also, you should note that the EVM uses the larger "ALV" package version of the AM243 while the LaunchPad uses the smaller "ALX" package version.

    Thanks,
    Mike

    Hi Mike,

    Thanks for the clarification regarding the evaluation boards.

    We plan to use AM2431BSDFHIALVR MCU, is this GP or HS silicon?

    Hi Praveen,

    If you take a look at the AM2431 Datasheet, section 10.1 has the Device Nomenclature table that includes a breakdown of all the different characters in the part number and what the character means.

    From the table, the 'H' means the device is "Secure".  This is is the "High Security" referred to in "HS".

    Thanks,
    Mike
